Mercedes 420SEL Replacement Oil Pump Information

Your Mercedes 420SEL's engine contains many moving parts that are necessary if the process of internal combustion is to transpire smoothly. These moving engine parts must be kept lubricated, or frictional forces will wear them down. Your Mercedes 420SEL's engine uses oil to lubricate its moving parts, and that oil is routed through the engine parts that need it through the action of your oil pump. PartsGeek.com sells oil pumps for the Mercedes 420SEL.

The oil pump is mounted inside your engine's oil pan, which is an oil reservoir located near the bottom front of your engine. Oil can only be pumped under pressure. An electronic sensor monitors the pressure in the oil pump and sends this information to your vehicle's electronic control unit. When your oil pressure is low, the red oil warning light will flash on in the dashboard instrument panel of your car.
